• This project focuses on feature preparation, gradient-boost algorithm training, and creating an API that would output recommendations in JSON format.
• Tools & Technologies: Python Jupyter Pandas Catboost FastAPI SQLAlchemy

• This project is using GPT-3.5 API, reads the PDF file with laws, breaks it down into vectorized chunks and fed to the GPT. The application is connected to the whatsup chatbot API where the user is able to have a chat with the bot that have the laws in his memory.
• Tools & Technologies: Python Flask twilio OpenAI API

• This project involves developing an AI-powered Tic-Tac-Toe game using adversarial search and the Minimax algorithm for optimal decision-making. The game, created for the CS50-AI course, employs techniques such as Alpha-Beta pruning to enhance efficiency.
• Tools & Technologies: Python Minimax Algorithm Alpha-Beta Pruning

• CS50-AI Project0-Degrees is the first assignment of CS50 AI, where the task is to implement an algorithm to find the shortest path between two actors without Kevin Bacon.
• Tools & Technologies: Python Minimax Algorithm Alpha-Beta Pruning

• This project is a Python-based AI solver for the logical "Knights and Knaves" puzzles using propositional logic and model checking.
• Tools & Technologies: Python Data Structures Search Algorithms File I/O Exception Handling

• This project presents an AI agent capable of playing the Minesweeper game intelligently. Developed as part of the CS50-AI course, the agent applies propositional logic to make safe moves and make inferences, reducing the chances of hitting a mine. When no safe move is discernable, the agent makes a random move. This project is a demonstration of the application of AI knowledge representation and reasoning in game playing.

• This project demonstrates the extraction of comments from a website using web scraping techniques, saving the comments in text and PDF formats, and the implementation of text processing to split the text into smaller chunks. It further uses OpenAI's DocumentSearch for finding relevant documents to a query and answers the query using OpenAI's Question-Answering chain.
